At the heart of the DoubleCross challenge is a course designed in the
Mirrorkhana-style of autocross, where two competitors enter and finish a
single course at different points. Using the traditional ProSolo
Christmas tree start, competitors essentially followed the same route
half a lap behind each other.

Saturday was composed entirely of class competition. Each driver received
three runs from each entry point on the course. To ensure legitimate
dial-ins for Sunday's elimination rounds, times were not posted for
any of the Saturday runs. The main purpose of Saturday's class
heats was to build a master index and divide the 155 entrants into five
equally distributed brackets for Sunday's elimination rounds.

A Stock and Street Touring Sport 2 were the largest fully subscribed
classes at 12 each. While AS had a lot of car diversity, STS-2 was
populated by the usual Miatas and CRX's. STS-2 competitors continue
to make a strong case for advancement to full National status in 2008
with another strong showing in Atlanta.

The novelties continued on Sunday as drivers had to lose twice to be
eliminated from one of the brackets. Additionally, two line judges were
used at the finish line to determine the winner of each heat. The top six
finishers in each bracket plus the two highest overall seeds to be
eliminated were sent on to the Hawk Super Challenge, run in traditional
single-elimination format. It all made for a long day indeed, but
Soloists benefited in the end with more runs than a traditional ProSolo
event.

The five bracket winners were Michael Johnson in an A Stock Prepared
Chevrolet Corvette, Steve Waters driving a Super Stock Chevrolet
Corvette, Mike King driving a Street Touring S2 Mazda Miata and both
Robert Carpenter and Mark Mccrary in a shared E Stock Toyota MR2.

The final match up of the Hawk Super Challenge was quite suspenseful. The
skies began to darken considerably and rain seemed imminent as Johnathan
Roberts' A Stock Subaru STi and Robert Carpenter's Miata
approached the start lines. The finish proved too close to call when the
two finish-line judges disagreed on a winner, thus the cars were sent
back to the starting boxes for another run. The second time around,
Carpenter came out the clear winner, taking his first-ever Hawk Super
Challenge win.

Of the 32 drivers in the Hawk Super Challenge, 12 were in Hondas for the
largest contingent of entries into the concurrently run Honda Tuner
Challenge during the 2007 season. The battle to determine the Honda Tuner
Challenge Hot Shoe of the event pitted Solo veteran Mike King in a Honda
CRX Si against high school senior Danny Carroll in an Acura Integra R.
Call it wisdom, experience, or just plain skill, King took the win and
the extra $250 prize.

Like Sunday's prequalification brackets, the Ladies Challenge was
run in a double elimination format and saw Ladies 1 class victor Karen
Kraus in a Subaru Impreza versus Ladies 2 runner-up Tara Knoll in a Honda
CRX Si. Kraus' Subie hit the finished line with half a car length
on Knoll, who had ironically been strictly a Subaru competitor until this
season. It was the second ProSolo win in a row for Kraus who also claimed
victory a week earlier in Washington D.C.

While the overall length of the event provided some challenges and the
format left several Soloists scratching their heads, the Atlanta
Region's DoubleCross Challenge was a compelling event for all
involved and appears to have a future in SCCA ProSolo.

"The Atlanta Region Solo Committee is to be commended for taking
the original Rocky Entriken and Salina Region Mirrorkhana to the next
level and creating an entertaining experience for the competitors,"
SCCA Vice President of Solo and Rally Howard Duncan said. "We were
pleased to make it part of the 2007 Tire Rack ProSolo season in this year
of experimentation and program development as it gave us a lot to think
about for 2008. The format presents difficulties for handling large
turnouts, but there is no doubt that it is intriguing and that at least
elements of what we saw will make it into our future plans."
